| 摘 要： | 尺寸公差模型对产品信息的完备性和尺寸驱设计都是极为重要的。常见的尺寸公差模型是对传统工程图尺寸标注的实现，缺少设计过程方面的理论支持。文章还提出了特的特征的尺寸模式生约束模式的概念，给出了实例并讨论其应用。

| Abstract: | Dimension and Tolerance(D & T)models are crictical for the information completeness of product models and dimension driven design.Existing D & T models are more or less versions of dimensioning of conventional drawings,and should be based on a sound design process theory.In this paper,the relationship of dimensions,constraints and design intent are discussed.A new D & T model(namely,SEDT model)based on feature semantics is proposed.SEDT is promising in analogical design and conceptual design.Dimension pattern,constraint pattern and related applications are also introduced. |
